    Notes: Abstract Mustard seedlings were light treated at 24 h after sowing (25°C) to induce phytochrome-mediated anthocyanin synthesis in cotyledons and hypocotylar hook. All light treatments were performed within the range of the reciprocity law. The in situ photoconversion kinetics of phytochrome (Pr→ Pfr) were measured under the same light treatment. It was found that between 0.4 and 1.0 relative Pfr level the amount of anthocyanin extracted from the organs at 52 h after sowing was linearily correlated with the amount of Pfr produced at 24 h in cotyledons and hypocotylar hook. It is concluded that an explanation of the fluence response function for red light mediated anthocyanin synthesis in the mustard seedling does not require the concept of active vs. bulk phytochrome.

    Rubidium and Potassium Absorption by Bean-leaf Slices Compared to Sodium Absorption (1973)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: At salt concentrations of 0.1 mM as well as of 5.0 mM, the 22Na+ absorption capacity of bean (Phaseolus vulgaris L. cv. ‘Brittle Wax’) leaf tissue increased during the period of leaf expansion and decreased rapidly after leaf maturation. The absorption capacity for 86Rb+ and 42K+ was highest in very young leaves and decreased continuously in expanding and in mature leaves. The 86Rb+ absorption capacity of mature leaves was not increased by detopping the plants; this senescence-retarding treatment more than doubled 2Na+ absorption.The absorption of 22Na+ by bean-leaf slices was not enhanced by light, whereas 86Rb+ and 42K+ absorption was much affected.Previously absorbed 86Rb+ and 42K+ were more available for exchange than 22Na+.
